7e577a17f2 Input: add I2C attached EETI EXC3000 multi touch driver
The 3000 series have a new protocol which allows to report up to 5 points
in a single 66 byte frame. One must always read in 66 byte frames.
To support up to 10 points, two consecutive frames need to be read:
The first frame says how many points until sync.
The second frame must say zero points or both frames must be discarded.

To be able to work with the higher 400KHz I2C bus rate, one must
successfully send a special package prior _each_ read or the controller
will refuse to cooperate.

This is a minimal implementation based on egalax_i2c.c (which can be found
on the internet) and egalax_ts.c but without the vendor interface and no
power management support.

d141babe42 locking/lockdep: Add a boot parameter allowing unwind in cross-release and disable it by default
Johan Hovold reported a heavy performance regression caused by lockdep
cross-release:

 > Boot time (from "Linux version" to login prompt) had in fact doubled
 > since 4.13 where it took 17 seconds (with my current config) compared to
 > the 35 seconds I now see with 4.14-rc4.
 >
 > I quick bisect pointed to lockdep and specifically the following commit:
 >
 >	28a903f63e ("locking/lockdep: Handle non(or multi)-acquisition
 >	               of a crosslock")
 >
 > which I've verified is the commit which doubled the boot time (compared
 > to 28a903f63ec0^) (added by lockdep crossrelease series [1]).

Currently cross-release performs unwind on every acquisition, but that
is very expensive.

This patch makes unwind optional and disables it by default and only
records acquire_ip.

Full stack traces are sometimes required for full analysis, in which
case a boot paramter, crossrelease_fullstack, can be specified.

On my qemu Ubuntu machine (x86_64, 4 cores, 512M), the regression was
fixed. We measure boot times with 'perf stat --null --repeat 10 $QEMU',
where $QEMU launches a kernel with init=/bin/true:

1. No lockdep enabled:

 Performance counter stats for 'qemu_booting_time.sh bzImage' (10 runs):

       2.756558155 seconds time elapsed                    ( +-  0.09% )

2. Lockdep enabled:

 Performance counter stats for 'qemu_booting_time.sh bzImage' (10 runs):

       2.968710420 seconds time elapsed                    ( +-  0.12% )

3. Lockdep enabled + cross-release enabled:

 Performance counter stats for 'qemu_booting_time.sh bzImage' (10 runs):

       3.153839636 seconds time elapsed                    ( +-  0.31% )

4. Lockdep enabled + cross-release enabled + this patch applied:

 Performance counter stats for 'qemu_booting_time.sh bzImage' (10 runs):

       2.963669551 seconds time elapsed                    ( +-  0.11% )

I.e. lockdep cross-release performance is now indistinguishable from
vanilla lockdep.

3587679d93 locking/atomics, doc/filesystems: Convert ACCESS_ONCE() references
For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't currently harmful.

However, for some features it is necessary to instrument reads and
writes separately, which is not possible with ACCESS_ONCE(). This
distinction is critical to correct operation.

It's possible to transform the bulk of kernel code using the Coccinelle
script below. However, this doesn't handle documentation, leaving
references to ACCESS_ONCE() instances which have been removed. As a
preparatory step, this patch converts the filesystems documentation to
use {READ,WRITE}_ONCE() consistently.

25309004c0 Input: goodix - support gt1151 touchpanel
Support was added based on Goodix GitHub repo [1]. There are two major
differences between gt1151 and currently supported devices (gt9x):
 * CONFIG_DATA register has 0x8050 address instead of 0x8047,
 * config data checksum has 16-bit width instead of 8-bit.

Also update goodix_i2c_test() function, so it reads ID register (which
has the same address for all devices) instead of CONFIG_DATA (because
its address is known only after reading ID of the device).

0cc2b4e5a0 PM / QoS: Fix device resume latency PM QoS
The special value of 0 for device resume latency PM QoS means
"no restriction", but there are two problems with that.

First, device resume latency PM QoS requests with 0 as the
value are always put in front of requests with positive
values in the priority lists used internally by the PM QoS
framework, causing 0 to be chosen as an effective constraint
value.  However, that 0 is then interpreted as "no restriction"
effectively overriding the other requests with specific
restrictions which is incorrect.

Second, the users of device resume latency PM QoS have no
way to specify that *any* resume latency at all should be
avoided, which is an artificial limitation in general.

To address these issues, modify device resume latency PM QoS to
use S32_MAX as the "no constraint" value and 0 as the "no
latency at all" one and rework its users (the cpuidle menu
governor, the genpd QoS governor and the runtime PM framework)
to follow these changes.

Also add a special "n/a" value to the corresponding user space I/F
to allow user space to indicate that it cannot accept any resume
latencies at all for the given device.

Fixes: 85dc0b8a40 (PM / QoS: Make it possible to expose PM QoS latency constraints)

2d5afd51fe usb: changes for v4.15 merge window
Not much going on this time around. With only 51 non-merge commits,
 this was one of the smallest pull requests from the Gadget tree.
 
 Most of the changes are in the mtu3 driver which added support for
 36-bit DMA, support for USB 3.1 and support for dual-role (along with
 some non-critical fixes).
 
 The dwc2 driver got a few improvements to how we handle gadget state
 tracking and also added support for STM32F7xx devices.
 
 Other than that, we just some minor non-critical fixes and
 improvements all over the place.

Merge tag 'usb-for-v4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

Felipe writes:

usb: changes for v4.15 merge window

Not much going on this time around. With only 51 non-merge commits,
this was one of the smallest pull requests from the Gadget tree.

Most of the changes are in the mtu3 driver which added support for
36-bit DMA, support for USB 3.1 and support for dual-role (along with
some non-critical fixes).

The dwc2 driver got a few improvements to how we handle gadget state
tracking and also added support for STM32F7xx devices.

Other than that, we just some minor non-critical fixes and
improvements all over the place.

59ecbbe7b3 locking/barriers: Kill lockless_dereference()
lockless_dereference() is a nice idea, but it gained little traction in
kernel code since its introduction three years ago. This is partly
because it's a pain to type, but also because using READ_ONCE() instead
has worked correctly on all architectures apart from Alpha, which is a
fully supported but somewhat niche architecture these days.

Now that READ_ONCE() has been upgraded to contain an implicit
smp_read_barrier_depends() and the few callers of lockless_dereference()
have been converted, we can remove lockless_dereference() altogether.

61011264c1 iio: dac: Add Texas Instruments 8/10/12-bit 2/4-channel DAC driver
The DACrrcS085 (rr = 08/10/12, c = 2/4) family of SPI DACs was
inherited by TI when they acquired National Semiconductor in 2011.
This driver was developed for and tested with the DAC082S085 built into
the Revolution Pi by KUNBUS, but should work with any of the other
chips as they share the same programming interface.

There is also a family of I2C DACs with just a single channel called
DACrr1C08x (rr = 08/10/12, x = 1/5).  Their programming interface is
very similar and it should be possible to extend the driver for these
chips with moderate effort.  Alternatively they could be integrated into
ad5446.c.  (The AD5301/AD5311/AD5321 use different power-down modes but
otherwise appear to be comparable.)

Furthermore there is a family of 8-channel DACs called DACrr8S085
(rr = 08/10/12) as well as two 16-bit DACs called DAC161Sxxx
(xxx = 055/997).  These are more complicated devices with support for
daisy-chaining and the ability to power down each channel separately.
They could either be handled by a separate driver or integrated into the
present driver with a larger effort.

12a8cc7fcf x86/kasan: Use the same shadow offset for 4- and 5-level paging
We are going to support boot-time switching between 4- and 5-level
paging. For KASAN it means we cannot have different KASAN_SHADOW_OFFSET
for different paging modes: the constant is passed to gcc to generate
code and cannot be changed at runtime.

This patch changes KASAN code to use 0xdffffc0000000000 as shadow offset
for both 4- and 5-level paging.

For 5-level paging it means that shadow memory region is not aligned to
PGD boundary anymore and we have to handle unaligned parts of the region
properly.

In addition, we have to exclude paravirt code from KASAN instrumentation
as we now use set_pgd() before KASAN is fully ready.

1f63fab955 dt-bindings: Document common property for daisy-chained devices
Many serially-attached GPIO and IIO devices are daisy-chainable.

    Examples for GPIO devices are Maxim MAX3191x and TI SN65HVS88x:
    https://datasheets.maximintegrated.com/en/ds/MAX31913.pdf
    http://www.ti.com/lit/ds/symlink/sn65hvs880.pdf

    Examples for IIO devices are TI DAC128S085 and TI DAC161S055:
    http://www.ti.com/lit/ds/symlink/dac128s085.pdf
    http://www.ti.com/lit/ds/symlink/dac161s055.pdf

We already have drivers for daisy-chainable devices in the tree but
their devicetree bindings are somewhat inconsistent and ill-named:

    The gpio-74x164.c driver uses "registers-number" to convey the
    number of devices in the daisy-chain.  (Sans vendor prefix,
    multiple vendors sell compatible versions of this chip.)

    The gpio-pisosr.c driver takes a different approach and calculates
    the number of devices in the daisy-chain by dividing the common
    "ngpios" property (Documentation/devicetree/bindings/gpio/gpio.txt)
    by 8 (which assumes that each chip has 8 inputs).

Let's standardize on a common "#daisy-chained-devices" property.
That name was chosen because it's the term most frequently used in
datasheets.  (A less frequently used synonym is "cascaded devices".)

eec1d566cd gpio: Introduce ->get_multiple callback
SPI-attached GPIO controllers typically read out all inputs in one go.
If callers desire the values of multipe inputs, ideally a single readout
should take place to return the desired values.  However the current
driver API only offers a ->get callback but no ->get_multiple (unlike
->set_multiple, which is present).  Thus, to read multiple inputs, a
full readout needs to be performed for every single value (barring
driver-internal caching), which is inefficient.

In fact, the lack of a ->get_multiple callback has been bemoaned
repeatedly by the gpio subsystem maintainer:
http://www.spinics.net/lists/linux-gpio/msg10571.html
http://www.spinics.net/lists/devicetree/msg121734.html

Introduce the missing callback.  Add corresponding consumer functions
such as gpiod_get_array_value().  Amend linehandle_ioctl() to take
advantage of the newly added infrastructure.  Update the documentation.

558b01654d irqchip/gic-v3: Add workaround for Synquacer pre-ITS
The Socionext Synquacer SoC's implementation of GICv3 has a so-called
'pre-ITS', which maps 32-bit writes targeted at a separate window of
size '4 << device_id_bits' onto writes to GITS_TRANSLATER with device
ID taken from bits [device_id_bits + 1:2] of the window offset.
Writes that target GITS_TRANSLATER directly are reported as originating
from device ID #0.

So add a workaround for this. Given that this breaks isolation, clear
the IRQ_DOMAIN_FLAG_MSI_REMAP flag as well.

686140a1a9 s390: introduce CPU alternatives
Implement CPU alternatives, which allows to optionally patch newer
instructions at runtime, based on CPU facilities availability.

A new kernel boot parameter "noaltinstr" disables patching.

Current implementation is derived from x86 alternatives. Although
ideal instructions padding (when altinstr is longer then oldinstr)
is added at compile time, and no oldinstr nops optimization has to be
done at runtime. Also couple of compile time sanity checks are done:
1. oldinstr and altinstr must be <= 254 bytes long,
2. oldinstr and altinstr must not have an odd length.

alternative(oldinstr, altinstr, facility);
alternative_2(oldinstr, altinstr1, facility1, altinstr2, facility2);

Both compile time and runtime padding consists of either 6/4/2 bytes nop
or a jump (brcl) + 2 bytes nop filler if padding is longer then 6 bytes.

.altinstructions and .altinstr_replacement sections are part of
__init_begin : __init_end region and are freed after initialization.

Present same interface as the regular cros_ec sensor stack:
- one iio device per accelerometer
- use HTML5 axis definition
- use iio abi units
- accept calibration calls, but do nothing

61b639723b mm, swap: use page-cluster as max window of VMA based swap readahead
When the VMA based swap readahead was introduced, a new knob

  /sys/kernel/mm/swap/vma_ra_max_order

was added as the max window of VMA swap readahead.  This is to make it
possible to use different max window for VMA based readahead and
original physical readahead.  But Minchan Kim pointed out that this will
cause a regression because setting page-cluster sysctl to zero cannot
disable swap readahead with the change.

To fix the regression, the page-cluster sysctl is used as the max window
of both the VMA based swap readahead and original physical swap
readahead.  If more fine grained control is needed in the future, more
knobs can be added as the subordinate knobs of the page-cluster sysctl.

The vma_ra_max_order knob is deleted.  Because the knob was introduced
in v4.14-rc1, and this patch is targeting being merged before v4.14
releasing, there should be no existing users of this newly added ABI.

eeb2d80d50 ACPI / LPIT: Add Low Power Idle Table (LPIT) support
Add functionality to read LPIT table, which provides:

 - Sysfs interface to read residency counters via
   /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
   /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us

Here the count "low_power_idle_cpu_residency_us" shows the time spent
by CPU package in low power state.  This is read via MSR interface,
which points to MSR for PKG C10.

Here the count "low_power_idle_system_residency_us" show the count the
system was in low power state. This is read via MMIO interface. This
is mapped to SLP_S0 residency on modern Intel systems. This residency
is achieved only when CPU is in PKG C10 and all functional blocks are
in low power state.

It is possible that none of the above counters present or anyone of the
counter present or all counters present.

For example: On my Kabylake system both of the above counters present.
After suspend to idle these counts updated and prints:

 6916179
 6998564

This counter can be read by tools like turbostat to display. Or it can
be used to debug, if modern systems are reaching desired low power state.

 - Provides an interface to read residency counter memory address

   This address can be used to get the base address of PMC memory
   mapped IO.  This is utilized by intel_pmc_core driver to print
   more debug information.

In addition, to avoid code duplication to read iomem, removed the read of
iomem from acpi_os_read_memory() in osl.c and made a common function
acpi_os_read_iomem(). This new function is used for reading iomem in
in both osl.c and acpi_lpit.c.

2b1516e55f rcutorture: Add interrupt-disable capability to stall-warning tests
When rcutorture sees the rcutorture.stall_cpu kernel boot parameter,
it loops with preemption disabled, which does in fact normally
generate an RCU CPU stall warning message.  However, there are test
scenarios that need the stalling CPU to have interrupts disabled.
This commit therefore adds an rcutorture.stall_cpu_irqsoff kernel
boot parameter that causes the stalling CPU to disable interrupts.

(R8A7743/5) usbdmac engine is identical to the R-Car Gen2 family.

No driver change is needed due to the fallback compatible value
"renesas,r8a7743-usb-dmac".
Adding the SoC-specific compatible values here has two purposes:
  1. Document which SoCs have this hardware module,
  2. Allow checkpatch to validate compatible values.

old document to the kernel source itself to allow for us to properly
reference it in one canonical place (as the LF wiki keeps moving things
around.)

This also will allow people to add their names to it, as I seem to have

41dcf197ad dm raid: fix incorrect status output at the end of a "recover" process
There are three important fields that indicate the overall health and
status of an array: dev_health, sync_ratio, and sync_action.  They tell
us the condition of the devices in the array, and the degree to which
the array is synchronized.

This commit fixes a condition that is reported incorrectly.  When a member
of the array is being rebuilt or a new device is added, the "recover"
process is used to synchronize it with the rest of the array.  When the
process is complete, but the sync thread hasn't yet been reaped, it is
possible for the state of MD to be:
 mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ]
 curr_resync_completed = <max dev size> (but not MaxSector)
 and all rdevs to be In_sync.
This causes the 'array_in_sync' output parameter that is passed to
rs_get_progress() to be computed incorrectly and reported as 'false' --
or not in-sync.  This in turn causes the dev_health status characters to
be reported as all 'a', rather than the proper 'A'.

This can cause erroneous output for several seconds at a time when tools
will want to be checking the condition due to events that are raised at
the end of a sync process.  Fix this by properly calculating the
'array_in_sync' return parameter in rs_get_progress().

Also, remove an unnecessary intermediate 'recovery_cp' variable in
rs_get_progress().

85fdee1eef ovl: fix regression caused by exclusive upper/work dir protection
Enforcing exclusive ownership on upper/work dirs caused a docker
regression: https://github.com/moby/moby/issues/34672.

Euan spotted the regression and pointed to the offending commit.
Vivek has brought the regression to my attention and provided this
reproducer:

Terminal 1:

  mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
        merged/

Terminal 2:

  unshare -m

Terminal 1:

  umount merged
  mount -t overlay -o workdir=work,lowerdir=lower,upperdir=upper none
        merged/
  mount: /root/overlay-testing/merged: none already mounted or mount point
         busy

To fix the regression, I replaced the error with an alarming warning.
With index feature enabled, mount does fail, but logs a suggestion to
override exclusive dir protection by disabling index.
Note that index=off mount does take the inuse locks, so a concurrent
index=off will issue the warning and a concurrent index=on mount will fail.

Documentation was updated to reflect this change.

XHCI specification 1.1 does not require xHCI-compliant controllers
to always enable hardware USB2 LPM. However, the current xHCI
driver always enable it when seeing HLC=1.
This patch supports an option for users to control disabling
USB2 Hardware LPM via DT/ACPI attribute.
This option is needed in case user would like to disable this
feature. For example, their xHCI controller has its USB2 HW LPM
broken.

42b76d0e6b ARM: SoC fixes for 4.14-rc
Our first batch of fixes this release cycle, unfortunately a bit noisier
 than usual. Two major groups stand out:
 
  - Some pinctril dts/dtsi changes for stm32 due to a new driver being
    merged during the merge window, and this aligns the DT contents between
    the old format and the new. This could arguably be moved to the next
    merge window but it also seemed relatively harmless to include now.
 
  - Amlogic/meson had driver changes merged that required devicetree
    changes to avoid functional/performance regressions. I've already
    asked them to be more careful about this going forward, and making
    sure drivers are compatible with older DTs when they make these kind
    of changes. The platform is actively being upstreamed so there's a
    few things in flight, we've seen this happen before and sometimes
    it's hard to catch in time.
 
 Besides that there is the usual mix of minor fixes.

On Armada 7K/8K we need to explicitly enable the bus clock. The bus clock
is optional because not all the SoCs need them but at least for Armada
7K/8K it is actually mandatory.

The binding documentation is updating accordingly.

Without this patch the kernel hand during boot if the mvpp2.2 network
driver was not present in the kernel. Indeed the clock needed by the
xenon controller was set by the network driver.

c4142ed602 Driver core fixes for 4.14-rc4
Here are a few small fixes for 4.14-rc4.
 
 The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one
 straggler made it in through some other tree (odds are, one of mine...)
 So there's a simple removal of the last user, and then finally the macro
 is removed from the tree.
 
 There's a fix for old crazy udev instances that insist on reloading a
 module when it is removed from the kernel due to the new uevents for
 bind/unbind.  This fixes the reported regression, hopefully some year in
 the future we can drop the workaround, once users update to the latest
 version, but I'm not holding my breath.
 
 And then there's a build fix for a linker warning, and a buffer overflow
 fix to match the PCI fixes you took through the PCI tree in the same
 area.
 
 All of these have been in linux-next for a few weeks while I've been
 traveling, sorry for the delay.

Also default settings to POR defaults on a reset, and register
distuber interrupts as noise since it prevents proper usage.

069f0e0c06 Round one of new device support, features and cleanup for IIO in the 4.15 cycle.
Note there is a misc driver drop in here given we have support
 in IIO and the feeling is no one will care.
 
 A large part of this series is a boiler plate removal series avoiding
 the need to explicitly provide THIS_MODULE in various locations.
 It's very dull but touches all drivers.
 
 New device support
 * ad5446
   - add ids to support compatible parts DAC081S101, DAC101S101,
     DAC121S101.
   - add the dac7512 id and drop the misc driver as feeling is no
     one is using it (was introduced for a board that is long obsolete)
 * mt6577
   - add bindings for mt2712 which is fully compatible with other
     supported parts.
 * st_pressure
   - add support for LPS33HW and LPS35HW with bindings (ids mostly).
 
 New features
 * ccs811
   - Add support for the data ready trigger.
 * mma8452
   - remove artifical restriction on supporting multiple event types
     at the same time.
 * tcs3472
   - support out of threshold events
 
 Core and tree wide cleanup
 * Use macro magic to remove the need to provide THIS_MODULE as part of
   struct iio_info or struct iio_trigger_ops.  This is similar to
   work done in a number of other subsystems (e.g. i2c, spi).
 
   All drivers are fixed and then the fields in these structures are
   removed.
 
   This will cause build failures for out of tree drivers and any
   new drivers that cross with this work going into the kernel.
 
   Note mostly done with a coccinelle patch, included in the series
   on the mailing list but not merged as the fields no longer exist
   in the structures so the any hold outs will cause a build failure.
 
 Cleanups
 * ads1015
   - avoid writing config register when it doesn't change.
   - add 10% to conversion wait time as it seems it is sometimes
     a little small.
 * ade7753
   - replace use of core mlock with a local lock.  This is part of a
     long term effort to make the use of mlock opaque and single
     purpose.
 * ade7759
   - expand the use of buf_lock to cover previous mlock cases.  This
     is a slightly nicer solution to the same issue as in ade7753.
 * cros_ec
   - drop an unused variable
 * inv_mpu6050
   - add a missing break in a switch for consistency - not actual
     bug,
   - make some local arrays static to save on object code size.
 * max5481
   - drop manual setting of the spi module owner as handled by the
     spi core.
 * max5487
   - drop manual setting of the spi module owner as handled by the
     spi core.
 * max9611
   - drop explicit setting of the i2c module owner as handled by
     the i2c core.
 * mcp320x
   - speed up reads on single channel devices,
   - drop unused of_device_id data elements,
   - document the struct mcp320x,
   - improve binding docs to reflect restrictions on spi setup and
     to make it explicit that the reference regulator is needed.
 * mma8452
   - symbolic to octal permissions,
   - unsigned to unsigned int.
 * st_lsm6dsx
   - avoid setting odr values multiple times,
   - drop config of LIR as it is only ever set to the existing
     defaults,
   - drop rounding configuration as it only ever matches the defaults.
 * ti-ads8688
   - drop manual setting of the spi module owner as handled by the
     spi core.
 * tsl2x7x
   - constify the i2c_device_id,
   - cleanup limit checks to avoid static checker warnings (and generally
     have nicer code).
